[0010] Preferably, the positioning assembly includes a support plate, the support plate is fixedly connected to the rotating shaft, a through hole is opened on the top of the support plate, and protrusions are symmetrically arranged inside the through hole, and the protrusions are elastic. Through the cooperation between the protrusions and the support frame, under the action of centrifugal force, the support frame slides inside the through hole. There are four through holes, and the four through holes are evenly distributed on the top of the support plate. The support frame is slidably connected inside the through hole. During operation, the motor drives the rotating shaft to rotate, and then the rotating shaft drives the support plate to rotate. Under the action of centrifugal force, extrusion is generated between the support frame and the protrusion, and as the rotation The faster the shaft speed is, the greater the centrifugal force the support frame is subjected to, causing the support frame to slide inside the through hole through the protrusion. At this time, the fixed rod drives the magnetic block to move toward the direction of the spring plate, so that the magnetic block is close to the magnetic plate. The outer wall of the support plate is fixedly connected with a spring plate, and the spring plate is elastic. When the centrifugal force applied to the support frame is reduced, the elasticity of the spring plate is utilized to make the spring plate drive the support frame to slide in the direction of the rotating shaft, and then the support frame is reset. One end of the support frame close to the spring plate is fixedly connected with a fixed rod, the fixed rod passes through the spring plate, and the fixed rod is fixedly connected to the spring plate. The fixed rod passes through the spring plate and is extended and fixedly connected to the magnetic block.

At this time, the magnetic block is far away from the magnetic plate, so that the mutual attraction between the magnetic block and the magnetic plate is small. Under the elastic force of the compression spring, the slider and the limit block squeeze the water pipe, so that the cross-sectional area of ​​the water pipe here becomes smaller, resulting in a larger water flow rate, thereby facilitating the cleaning of the material receiving cylinder, and at the same time avoiding water splashing with too fast flow rate during stirring. The magnetic plate is located at the end of the extension plate away from the positioning cylinder, and the end of the slider close to the slide rod is fixedly connected with a compression spring, and the end of the compression spring away from the slider is fixedly connected to the extension plate.

[0012] Preferably, the outer wall of the collecting cylinder is rotatably connected to a rotating rod, and the rotating rod passes through the collecting cylinder. The outer wall of the rotating rod is fixedly connected to a rotating plate. There are several rotating plates, and the several rotating plates are evenly distributed on the outer wall of the rotating rod. The rotating plate is located inside the collecting cylinder.

[0013] The present invention provides a filtering and cleaning device for lotus root starch processing, which has the following beneficial effects:

[0014] 1. The filtering and cleaning equipment used for lotus root powder processing drives the fixed plate to rotate through the rotating shaft, so that the fixed plate drives the cleaning brush to clean the inner wall of the material receiving cylinder to avoid clogging of the circular holes at the bottom of the material receiving cylinder, thereby affecting the work efficiency. At the same time, the inner wall of the material receiving cylinder can be cleaned after the filtration is completed. When the material receiving cylinder moves up and down, extrusion is generated between the inner wall of the material receiving cylinder and the cleaning brush, and the cleaning brush is deformed by the force, so that the material receiving cylinder collides with the ball to avoid clogging of the material receiving cylinder, effectively clean the lotus root residue on the material receiving cylinder, and improve the filtering effect.

[0015] 2. The filtering and cleaning equipment used for lotus root powder processing drives the scraper to rotate through the rotating shaft to stir the material inside the material receiving barrel. The material at the bottom moves upward with the spiral plate to speed up the filtration efficiency. At the same time, the inside of the material receiving barrel is cleaned to avoid clogging of the round holes on the material receiving barrel and affect work efficiency.

[0016] 3. The filtering and cleaning equipment used for lotus root powder processing is provided with a cylinder on the top of the material receiving cylinder, so that during the filtering and stirring process, the material inside the material receiving cylinder is prevented from splashing everywhere, which makes it difficult to clean. The outer edge of the material receiving cylinder is located inside the guide groove. Through the sliding cooperation between the material receiving cylinder and the guide groove, it plays a guiding role in the process of the material receiving cylinder moving up and down, avoiding the deviation of the material receiving cylinder and the collision with the frame, which causes damage to the equipment.

[0017] 4. The filtering and cleaning equipment used for lotus root starch processing has opposite magnetism between the magnetic block and the magnetic plate, slow shaft rotation speed, and small centrifugal force on the supporting frame. At this time, the magnetic block is away from the magnetic plate, so that the mutual attraction between the magnetic block and the magnetic plate is small. Under the elastic force of the compression spring, the slider and the limit block squeeze the water pipe, so that the cross-sectional area of ​​the water pipe here becomes smaller, resulting in a larger water flow rate, which is convenient for cleaning the material holding barrel and avoids splashing of water due to excessively fast flow rate during stirring.

[0018] 5. The filtering and cleaning equipment used for lotus root starch processing moves the magnetic block toward the spring plate. When the magnetic block approaches the magnetic plate, the mutual attraction between the magnetic block and the magnetic plate is used to make the magnetic plate drive the slider to slide toward the magnetic block inside the extension plate, so that the slider moves away from the water pipe. The cross-sectional area of ​​the water pipe becomes larger here, which reduces the water flow rate and makes it easier to control the water flow rate according to different rotation speeds, thereby improving the filtering and cleaning effect.

[0019] 6. The filtering and cleaning equipment used for lotus root powder processing utilizes the weight of the material itself to make the rotating plate drive the rotating rod to rotate inside the collecting cylinder. At this time, the positioning rod in contact with the outer wall of the rotating rod moves up and down under the uneven shape of the positioning groove, and then the material receiving cylinder moves up and down in the guide groove along with the positioning rod, thereby avoiding blockage of the material receiving cylinder, improving the filtering efficiency, and facilitating the cleaning of the material receiving cylinder.

A limiting groove 65 is provided at one end of the fixing plate 64 close to the material receiving tube 5. The inside of the limiting groove 65 A ball 66 is fixedly connected, and the ball 66 is made of rubber. The ball 66 is higher than the groove height of the limiting groove 65. By arranging the ball 66 at the bottom of the cleaning brush 67, the ball 66 does not rub against the inside of the material receiving tube 5 during operation, thereby avoiding unnecessary loss and achieving the effect of knocking and cleaning.

A through hole 623 is provided on the top of the support plate 621. Protrusions are symmetrically arranged inside the through hole 623, and the protrusions are elastic. Through the cooperation between the protrusions and the support frame 624, under the action of centrifugal force, the support frame 624 slides inside the through hole 623. There are four through holes 623, which are evenly distributed on the top of the support plate 621. The support frame 624 is slidably connected inside the through hole 623. During operation, the motor 9 drives the rotating shaft 61 to rotate, and then the rotating shaft 61 drives the support plate 621 to rotate. Under the action of centrifugal force, extrusion is generated between the support frame 624 and the protrusion. As the rotation speed of the rotating shaft 61 increases, the support frame 624 is affected. The greater the centrifugal force, the greater the support frame 624 slides inside the through hole 623 through the protrusion. At this time, the fixed rod 625 drives the magnetic block 626 to move toward the spring plate 622, so that the magnetic block 626 is close to the magnetic plate 79. The outer wall of the support plate 621 is fixedly connected with the spring plate 622, and the spring plate 622 is elastic. When the centrifugal force on the support frame 624 is reduced, the elastic performance of the spring plate 622 is utilized to make the spring plate 622 drive the support frame 624 to slide in the direction of the rotating shaft 61, and then the support frame 624 is reset. The end of the support frame 624 close to the spring plate 622 is fixedly connected with the fixed rod 625, the fixed rod 625 penetrates the spring plate 622, and the fixed rod 625 is fixedly connected to the spring plate 622. The fixed rod 625 penetrates the spring plate 622 and is extended and fixedly connected with the magnetic block 626.

[0039] The spray mechanism 7 includes a positioning cylinder 71, which is fixedly connected to the inner wall of the frame 2. The interior of the positioning cylinder 71 is fixedly connected to a limiting plate 72. A water pipe 73 is provided inside the positioning cylinder 71. One end of the water pipe 73 is located at the opening of the material receiving cylinder 5. During the cleaning process, one end of the water pipe 73 located at the bottom of the frame 2 is connected to an external water source, so that water can enter the interior of the material receiving cylinder 5 through the water pipe 73, and then rinse the inner wall of the material receiving cylinder 5. The water pipe 73 contacts the end of the limiting plate 72 away from the positioning cylinder 71. An extension plate 74 is fixedly connected to the interior of the positioning cylinder 71. A through hole is provided inside the extension plate 74. The slider 76 is located at the through hole. Inside, the water pipe 73 passes through the extension plate 74 through the through hole, the extension plate 74 and the support plate 621 are located on the same horizontal plane, the extension plate 74 passes through the positioning tube 71, the end of the extension plate 74 close to the positioning tube 71 is fixedly connected to the limiting block 75, the extension plate 74 is slidably connected to the inside of the slide block 76, the water pipe 73 is located between the limiting block 75 and the slide block 76, the end of the slide block 76 away from the water pipe 73 is fixedly connected to the slide bar 77, the slide bar 77 passes through the extension plate 74, and the end of the slide bar 77 away from the slide block 76 is fixedly connected to the magnetic plate 79.

Under the elastic force of the compression spring 78, the slider 76 and the limit block 75 squeeze the water pipe 73, so that the cross-sectional area of ​​the water pipe here becomes smaller, resulting in a larger water flow rate, which is convenient for cleaning the material holding cylinder 5 and avoids splashing of water with too fast a flow rate during stirring. The magnetic plate 79 is located at the end of the extension plate 74 away from the positioning cylinder 71, and the end of the slider 76 close to the slide rod 77 is fixedly connected to the compression spring 78, and the end of the compression spring 78 away from the slider 76 is fixedly connected to the extension plate 74. During the cleaning process, the motor 9 rotates to drive the rotating shaft 61 to rotate. As the rotation speed of the rotating shaft 61 changes, the supporting frame 624 is driven to slide inside the through hole 623, so that the magnetic block 626 moves toward the spring plate 622. When the magnetic block 626 approaches the magnetic plate 79, the mutual attraction between the magnetic block 626 and the magnetic plate 79 is used to make the magnetic plate 79 drive the slider 76 to slide inside the extension plate 74 toward the magnetic block 626, so that the slider 76 moves away from the water pipe 73.

[0040] The third embodiment is based on the first and second embodiments. Figures 9 and 10As shown, the outer wall of the collecting barrel 86 is rotatably connected to a rotating rod 81, and the rotating rod 81 passes through the collecting barrel 86. The outer wall of the rotating rod 81 is fixedly connected to a rotating plate 82. There are several rotating plates 82, and several rotating plates 82 are evenly distributed on the outer wall of the rotating rod 81. The rotating plate 82 is located inside the collecting barrel 86. The outer wall of the rotating rod 81 is provided with a positioning groove 83. The surface of the positioning groove 83 is uneven. The positioning grooves 83 are symmetrically arranged at both ends of the rotating rod 81. The bottom of the material receiving barrel 5 is fixedly connected to a positioning rod 84. During the working process, the filtered material falls onto the rotating plate 82. The weight of the material itself is used to make the rotating plate 82 drive the rotating rod 81 to rotate inside the collecting barrel 86. At this time, the positioning rod 84 in contact with the outer wall of the rotating rod 81 is uneven in the positioning groove 83. In a flat shape, it moves up and down, and then the material receiving cylinder 5 moves up and down in the guide groove 10 with the positioning rod 84, avoiding clogging of the material receiving cylinder 5, improving the filtration efficiency, and facilitating the cleaning of the material receiving cylinder 5.

[0041] When in use, the motor 9 drives the rotating shaft 61 to rotate, and then the rotating shaft 61 drives the fixing plate 64 to rotate, so that the fixing plate 64 drives the cleaning brush 67 to clean the inner wall of the material receiving tube 5. At the same time, the rotating shaft 61 drives the supporting plate 621 to rotate. Under the action of centrifugal force, extrusion is generated between the supporting frame 624 and the protrusion. As the rotating speed of the rotating shaft 61 is faster, the centrifugal force on the supporting frame 624 is greater, so that the supporting frame 624 slides inside the through hole 623 through the protrusion. At this time, the fixing rod 625 drives the magnetic block 626 to move toward the spring plate 622, so that the magnetic block 626 approaches the magnetic plate 79. By utilizing the mutual attraction between the magnetic block 626 and the magnetic plate 79, the magnetic plate 79 drives the slider 76 to slide inside the extension plate 74 toward the direction of the magnetic block 626, so that the slider 76 is away from the water pipe 73. Here, the cross-sectional area of ​​the water pipe 73 becomes larger, so that the flow rate of water is reduced, which is convenient for controlling the flow rate of water according to different rotation speeds, thereby improving the filtering and cleaning effect.
